Last night Nebula suddenly errored on me and even crashed my daw c0000005. First it crashed on VCult, and now every instance just shows init, FTP = 0 Hz (instead of 96000). It just gives a low screaching sound... It tries to debug and says 8: missing authorization.

Do I need to reinstall the full version and then the upgrade .504 64 bit? I have the .ser file and the AITB libraries are AUT too...? So strange.

Don't believe it,
That happened to me last night too , this must be the same problem.I really need to get this sorted , i'm doing a project for someone right now.

Yes! I need to get a project done today as well. The computer isn't even connected to the internet. A timebomb? I backed up the xml's but wanted to ask for help on the forum before re-installing etc. Hope it'll get sorted out quickly.

Perhaps a long shot but the last thing I did before it stopped working was to download a new authorization for my UAD-1 card. It reset all my demos for that card. Could it be that it messed with the registry and therefore broke my Nebula licence?

Here's an emergency fallback if you - like me - tried to press "render" on a very important project on a timeline and then noticed that all 50 nebula instances are set to what the OP wrote (0 Hz, authorization missing etc.) and your mix sounds like crap:

- Uninstall nebula
- Set back system time to somewhere in April
- Install nebula with the oldest installer you can find (Setup, I tried with 1.5.464 or something)
- Upgrade to current 504 (Upgrade)
- Now there's no "program #0 invalid" anymore - you can render your stuff, everythings fine.
- Wait until the devs have sorted this out.

Basically the problem lies within that starting from today the most current installers can't generate valid Init.N2P and .N2V. So when you install from a current installer, it'll go immediately to "program #0 invalid" or "authorization missing", not generating .SER etc.
